This may be directory permission issue. For ex. if _`/var/lib/elasticsearch`_ is owned by root and service is running as elasticsearch user. Everything under _`/var/lib/elasticsearch`_ should be owned / writable by the user running elasticsearch service. ---

Hi Uli I found `Caused by: java.nio.file.NoSuchFileException: /var/lib/elasticsearch/nodes/0/node.lock` in the logs. Can you check if the file `/var/lib/elasticsearch/nodes/0/node.lock` exists? If not try `sudo touch /var/lib/elasticsearch/nodes/0/node.lock` This will create a zero byte file.. Then change ownership of this file to elasticsearch and permissions to 644. ---

Hi Vinayak, I deleted that file following another advice und cerated ist now as you said: touch /var/lib/elasticsearch/nodes/0/node.lock and set permissions to 644 chmod 644 /var/lib/elasticsearch/nodes/0/node.lock but it doesn't start _`systemctl start elasticsearch.service`_ Job for elasticsearch.service failed because the control process exited with error code.

Hi Uli Looks like you have moved past the "lock" issue. elasticsearch.yml you posted in your first post `transport.host` was misspelled as `nsport.host`. In the latest post, it is misspelled again `transsport.host:`. Is \* present as the first character on each line? If yes, that's an issue too. Setting transport.host to localhost means you cannot expand the cluster as no other node will be able to reach this node on 9300. Comment out the line `nsport.host`. Also, if you may want to use special values for network.host as describe [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) ```auto network.host: 192.168.10.3 # # Set a custom port for HTTP: # http.port: 9200 #transport.host: localhost transport.tcp.port: 9300 xpack.ml.enabled: false ``` ---

Hello Vinayak, I am am terribly to inform you that the modifications in elasticsearch.ym didn't change anything. Same error as before.

Uli, If your setup has multiple issues it will take iterations to solve them one by one. I just noticed in your first post you mentioned elasticsearch-oss. This version does not include x-pack plugin. So delete _`xpack.ml.enabled`_ line from yaml. ---

I am assuming - This is your local development environment. Before setting up a shared or a production cluster you must read [https://www.elastic.co/guide/en/elasticsearch/reference/7.8/setup.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/setup.html). - You are not planning to add more nodes to the ES cluster. If you are, then you need to read setup guide. - You want this ES to be accessible from a host other than 192.168.10.3. If the application accessing ES is running on the same host (192.168.10.3), this is typical in a development environment, just comment the network.host line. Then other application can access it as [http://localhost:9200](http://localhost:9200) If these 3 assumptions are valid add following line to elasticsearch.yml `discovery.seed_hosts: 192.168.10.3` Then the other application will be able access it using [http://192.168.10.3:9200](http://192.168.10.3:9200) **Must read** [https://www.elastic.co/guide/en/elasticsearch/reference/7.8/network.host.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/network.host.html) [https://www.elastic.co/guide/en/elasticsearch/reference/7.8/discovery-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/discovery-settings.html) [https://www.elastic.co/guide/en/elasticsearch/reference/7.8/modules-network.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/modules-network.html) ---

Hello Vinayak, Many thanks again for your help. Following your advice I got elasticsearch and logstash running now. Neither filebeat nor metricbeat I was able to get running and instead of Kibana I will use prometheus and grafana. (bothe are running yet). What I didn't found out yet is how I have to edtit the .yml files so that my elasticsearch host monitors all devices in my network and waht is the logstash index that grafana asks for. Best regards, Uli ---
